Referring now in greater detail to the'drawings where like reference numerals indicate like parts, reference numeral 10 indicates the collapsible chair, 11 the outer-receptacle, and 12 the disposable inner receptacle.

The chair It) is constituted of a seat member13,.a back member 14, front leg members 15 and16, and arm members 17 and 18. I

froiit member 19. The outer ends of the side members ends of the front member. *Over the top edges of the along illlll of Figure three sided frame is a platform 22, made from any suit reccssarethejarcuatesegments and 58(Figs. 6 and 11).

operated by the thumb screws 26, so that'in' coaction With the circumferential recess of the annular member, the segments 25 and 58'form a clamp for the removable insertion of the" outwardly and downwardly directed flange 57 of the later described outer receptacle 11 when insorted inthe seat member. The thumb scr'ews'26 are transversely inserted through the bottom of the annular member and their threaded into the segments.

' The back member 14 is constituted of the upstanding members 27 and 28 held'in spaced parallel arrangement by the three braces 29, 30, and 31, one of which (29) is adjacent the top and the other two intermediate the ends of theiupstandingi members. A back rest 32 (Figs. 1 and 2-)- is fastened in any known manner over the front of the braces--29 and 30 aiid the upper portions of the upstanding members' The bottom ed eof. the back rest 32 is'in upwardly paeed relationship with the inner edge of the platfo'r m 22 when the seat member is attached to the" of .the: plat-fllil' over the front of the back rest.

The. front legs 15 and 16 are pivotally secured at the top to the inner siitface of the side members '20 and 21 adjacentthe' front member 19 by the similar brackets 33', as "most clearly shown in Figure 9.- one end of each back member, as later shown to permit collapsing'the top en'disfastened to the corresponding surface of the leg member by screws or the like. A lip 35- (Fig. 9) is iri= tegrally? forfned with'the bracket and so designed that in theoped position of the legs (Fig. 9)'the lip will extend member 13 (Fig. 4).

. of the "chair;

fo'fi'wardly under the front member 19 for the additional support-thereof. By the construction described'and illustinted, the front legs are inwardly collapsible on the bot-.- torn surfaces ofthe side membefs 20 and 21 of the seat Reference numeral 16c: indicates abrace' for the front le'g member's.

yThe previously described side members 2lland 21 at theback afe pivotally secured to the inner surfaces of the upstanding members 27 and 28 intermediate the braces clearly shown in Figures 10 and 13.

by similar pivot pins 40 adjacent the bottom of thevbrace' 30, 'while the pposite end is turned forwardly and fastened by the screws 41 (Fig. 10) to the inner surfacc of the eeiresp i di g sidem'ember.

si-(i ig'. 13') directed toward the opposite upstanding member and integrally formed with the bracket. In the oiiti edge and inwardly directed in each protuberance is a. slot 38' (Fig. 13) designed to be en aged by the following described locking red 39 in the open position The locking rod 39 may be made of metal and of circiilaf cross section and is reeiprocable on the like bolts 42 (Fig. 5.) which are transversely inserted'through thebraces-Bfl and 31 and fastened thereb'etween. Sn

each bolt. 42 is a land 43 which scfveas stops when 1; the similar pins 44, axially directed from. each end of' the locking rod 39, are in the slots 38 to lock the seat and H I Along the bottom edge of each braeketlilfi adjacent the apex is a protuberance.

3 I back members in the open position, as well as the front leg members as later shown. (Fig. 5) maintain the pins under upwardly directed tension in the slots when the seat and back members are in the open position. By pressing downwardly on the bar 39 against the tension of the springs 45, the pins 44 are removed from the slots 38 to permit the top surface portion of the platform 22 to be collapsed on the front surface portion of the back rest 32 or conversely. By rounding the rear edges of the brackets adjacent the slots (Fig. '10), the chair will open without the necessity for manipulating the bar, since the rounded edges act as cams to push the pins out of the way prior to entering the slots under the tension of the springs. The chair is as operable with one pin in one end of the bar coacting with a slot in only one of the brackets as with both pins, as illustrated and described.

The upstanding members 27 and 28 and the front leg members and 16 are pivotally secured together at the bottom by the similar links 46 and 47 (Figs. 1 and 2). At the front, one end of each link is pivotally secured to the outer surface of a front leg member while at the back each link has formed therein a. longitudinal slot 48 (Figs. 2 and 4) in which a pivot pin 49, 'fixed at one end in the upstanding member, is slidable, such construction being essential for the collapsing operation. The arm members 17 .and 18 are constituted of the arm supports 49a and 50, respectively, each of which at the back is pivotally secured to the outer surface of the corresponding upstanding members 27 and 28, respectively, by the like pivot pins 51 (Figs..2 and 4). An

arm brace 52 (Figs. 1 and 2) is pivotally hinged at one end to the arm rest 50 by the pivot hinge 54adjacent the front, the hinge being pivotally secured :'at:one end by the pivot pin 55 to the inner surface of the arm rest with the opposite end fastened to the innersurface of the arm rest support by screws or the. like. The opposite end of the arm brace 52 is pivotally secured to the outer surface of the corresponding side member 21. A similar arm brace 56, similarly attached between the arm rest 49a and the side member 20, supports the arm rest 49a in the open position and permits the collapse thereof in the closed position.

The outer receptacle 11 is a flexible cylindrical memher with closed bottom and open top. Around the open top is an outwardly and downwardly directed rim 57 (Figs. 7 and 11) for removable insertion between the circular member 24'and the arcuate segments -and 58 which are made adjustable relative to; the. inner edge of the recess in the annular member by the thumb screws 26, as previously stated. The arcuate-segments may be made of resilient material as an aid in bringing the segments in close relationship with the outercdge of the recess to form a substantial clamp for the rim 'of the outer receptacle. Of course, the outer-receptacle'could be made of flexible material with the rim merely outwardly directed and permanently attached in a known manner around the periphery of the opening, since the flexible character of the outer receptacle'would not inter-' fere with the complete collapsing of the chair.

The disposable inner receptacle 12 (Figs. 8 and 12) is made from substantially flexible and water repellent material and is constituted of the similar superposed members 59 and 61. As shown in Figure 8, each member 59 and 61 is constricted between the top and bottom. The superposed bottom edges and the superposed side edges upwardly from the bottom edges substantially to the cone stricted portion are sealed in a known manner, so that the top portion of the receptacle can be spread out over the platform 22, as most clearly shown in Figure 3 after the inner receptacle is inserted in the outer receptacle. Of course, the inner receptacle may take a different shape and may be made from more than two members or even from one member.

Similar spiral springs 45 In operation: Assume that thechair is in the collapsed position shown in Figure 4, by pulling upwardly on the back rest 32 with one hand while holding the front of the seat member 13 firmly with the other hand, the seat,

back, front leg, and arm rest members will move tothe] open position, as illustrated in Figure 2. By separating the arcuate segments 25 and 58 from the outer edge of the recess in'the annular member 24 by the manipulation of the thumb screws 26, the downwardly directed portion of the rim 57 of the outer receptacle 11 can be inserted between the annular member and the segments p and the thumb screws tightened for clamping the rim in the seat member with the receptacle downwardly direct i The disposable inner I receptacle 12 is then inserted into the outer receptacle ed in the opening (Figs. 1 and 2).

through the open top thereof and the top portions of the inner receptacle spread the platform 22.
